Overview of the Cryogenic Detector and Development of the Cryogenic Inner Veto for the Observation of Coherent Elastic Neutrino Nucleus Scattering (CEνNS) with NUCLEUS10g — •Michael Hock — Technische Universität München

The study of Coherent Elastic Neutrino Nucleus Scattering (CEνNS) offers new opportunities to investigate fundamental neutrino properties and to probe physics beyond the Standard Model. The NUCLEUS experiment aims to precisely measure the CEνNS cross-section from electron antineutrinos produced at the reactors of the Chooz nuclear power plant in France.

NUCLEUS targets ultra-low recoil energies by employing gram-scale cryogenic calorimeters with energy thresholds on the order of O(10 eV). In its first science phase, NUCLEUS 10g will deploy two detector modules, each comprising nine cryogenic target detectors embedded in a Cryogenic Inner Veto.

This contribution presents the current status of the NUCLEUS 10g detector components and reports on the ongoing development of the Cryogenic Inner Veto, which is expected to mitigate the Low Energy Excess (LEE) and therefore may be essential for achieving the required low-background conditions.
